Substitute for abandoned application Serial No. 830,758, filed April 9,1914. This application filed May 16, 1918. Serial No. 235,040.

To all `whom, t may concern:

Be it known that I, ELIZABETH STACK- I'oLE, a citizen of the UnitedStates, residing at Canton, county of Stark, State of Ohio,admlnistratrix of the estate of RALPH D. STAcKroLE, late a citizen ofthe United States, and a resident of Canton', in the county of Stark andState of Ohio, deceased, (as by reference to the duly certified copy ofletters of administration heretol annexed will more fully appear.) dohereby declare that the ,said RALPH l). STACKPOLE invented a new anduseful Improvement in Tabulators for 'lype-lVriters, of which thefollowing is a specification. y

Tl invention has reference to improvements in typewriting machines ofthe poweractuated-ean'riage class, and its object is to provide for' thefeeding of the carriage :in either direction to any desired extent, frompredetermined points, and particularly for permitting the operator toproduce columns of figures or other similarly associated indicia wherecertain, and particularly terminal parts of the lgri-oups of figuresshould come directly one under the other.

The present invention is especially useful in writing columns of figuresdenoting values where the decimal points or those portions of theamounts represented which would agree with the decimal points should allbe in the same upright colum'n.

By the present invention the desired 0bject is attained by means of atabulator and appropriate mechanism connected therewith, together withmeans for reversing the direction ot' feed of the carriage, and thearrangement is such that the carriage stops at what may be termed thedecimal side of the column. and then feeds in the opposite direct-on toits normal feedingr movement, the operator writing the desired amounthackwarflly. that is, writing,r in the order of units, tens. hundreds,etc. V,

lt is an important feature of the present invent ion that the tabulatorbar and the reversingir mechanism are under the control of a single key,so that the carriage is released to move as far as the present positionon the tabolator bar, and then theteeding;r mechanism is reversed withrespect to the carriage, and the parts are locked in such position soloupr as the reversal of the movement of the carriage is desired.

Subordinate to this feature the invention provides a take-up mechanismso arranged that upon resetting the feed mechanism to cause the -arriageto resume its customary direction of travel. the power consumed in thereverse travel of the carriage is compensated for or restored, whereforethe propelling spring.;l is always under the same dcgree of tensionwhich it has in the ordinary normal action of the typewriter. i

The restoring mechanism is by the present invention utilized forunlocking the reversing mechanism when it is desired to again place thecarriage in position for normal operation, the common operating key forthe feeding mechanism and tahulator bar beingr locked in the operatedposition for reversing the direction of feed.

The invention also includes means associated with the common controllingkey for the tabulator bar and feed reversing mechanism, whereby themanipulation of the key first moves the tabulator bar into operativeposition and releases the carriage, and then further movement of the keyin the active direction is arrested until the carriage reaches the fulllimit of its predetermined movement after release, whereupon by means ofmechanism responsive to the momentum of the carriage the key ispermitted to more progressively for a farther distance, thereby bringingabout the settingr of thel carriage feed in a manner to cause thecarriage to move in the reverse direction to its normal direction ofmovement under the otherwise ordinary operation of tho-typewriter. Theparts controlled by the key under consideration are maintained in theactuated position b v a suitable lock which may be made responsive tothe before mentioned power restoring or compensating nteehanism,

The invention will loe best understood from a consideration of thefollowinrlr detaileddescription` taken in connection with theaccompanying drawings forming a part of this specification` with thefurther underchanges and modifications mark no material4 departure fromthe salient features ot' the invention., as claimed..

The present invention is show-n in the drawings as applied to a knownform of type-writing machine, the special construction of typewritershown being that'known in the trade as Remington No. fi. but it will heunderstood that the structure is susceptible o' many.changes adapting itto .lilferent forms of typewriter machines other than the particular oneillustrated. and this without any material change in the principalfeatures of the invention and embodying onliY such mechanical variationsin form, relation and proportions of the parts as may lie demanded inthe adaptation of the invention to other constructions of typewritinp`machines.

In the machine shown there a main frame l. a carriage 2 including theusual platen or rolle' 3, and a keyboard et. ln the drawings many of theparts entering into the ordinary construction of the typewriter haveheen omitted as unnecessary for an understanding of the invention, andwhich if shown would only serve to confuse the illastratioi'i of thoseparts particularly included in the present invention.

1n the particular showing of the drawings there is indicated a springarbor 5, spring ratchet wheel`6. double-acting paw] 7, spring` S, andincomplete volntil hand wheel 9, all as ordinariliT present in theparticular form of typewriting machine illustrated. hut instead of thespring and associated parts hcing mounted inside of the frame 1. thearbor 5, has a journal support upon a bracket 10 erected on the usualrear extension 10El of the main frame provided for the housingil of thepivot supports of the keys of the kev-hoard 4. Because ofthe rear 'arddisplacement of the spring and associated parts in the particulararrangement of the structure illustrated in. the drawings.y the arhor 5is correspondingly elongated, so that it may, as is customary in theparticular form of typewriter shown in the drawings. actuate the ribbonfeed` but such feed havingr nothing! to do with the present invention.is not illnstrated.

Likewise there is provided an rscalwmcnt arhor 11 mounted in anelongated journal hearing 1Q secured on top of the. frame l. as iscustomary. hut the arhor 11 is made longer than usual to provide for therearward disv placement of the spring.r and associated parts, and madefast to this arhor near its rear end is a pulley 13 to which is securedone end of a hand or strap 14t the other end Siti of this strap beingsecured to the rim of the Wheel 9 by a screw 15, as is customary. It isusual to fasten the strap 14 directly to the carriage of the typewriter,but in the structure of the present invention the band or strap actsdirectly on the escapcment arbor through the pulley 13 to rotate sucharbor, and by mechanism to be described the rotative movements of thearbor are imparted to the typewriter carriage in a manner to move thesame on the usual supporting tracks )rovided for the purposes, thesetracks being Indicated at 16 and 17, respectively, but being common totypewriting machines need no particular description. The track 16 issupported at the ends upon upstanding 'posts i 18 usually cast on thetop of the frame 1.

At the rear portion of the top of the trame i 1 and midway ofthe lengththereof there is secured an upstanding plate 19 provided with an an lefoot or base portion 20 by means of wiich the plate is made fast to thetop of the frame of the machine b v screws or otherwise. The arbor 11passes freely through the plate 1t) by way ot a slot 21, and adjacent tothe rear face of the plate 19 the arbor 11 Carries an escapement ratchetwheel 22 with which engage escapement dogs 23, 24 on opposite sides ofthe arbor 11, these dogs being pivotallv hung on a screw stud 25 carriedby the plate la at an appropriate distance above the arbor 11. 4The dogs23 and 24 between their pivot support 25" and the cscapcment ratchet 22have matching and facing recesses 2G approaching toward .the ratchetwheel. Unc of 'the dogs, say, the dog 23, is provided with anoffstanding arm 27 at 4an angle to the length of the dog, and this armis connect ed to a pull rod 28 leadin to the escapement controllingmembers o the typewriter, so that on the actuation of the keys of thekeyboard the esca ement will be operated in thel usual way. T e dogs areelastic-ally held onel in contact with the other adjacent to therecesses 26 by a connecting spring 29 pern|it ting the separation of thedogs under circumstances to be described.

4The escapelnent dogs 23 and 24 are under the control of certainmechanism forming part of the present invention, which mechanism, itsmannerof operation, and the func tions` performed, will be describedhereinafter, it being understood that the escapement is operated forreleasing the carriage to the ower Aspring 8 for step by step movement:1n thc usual mannerof voperation ot' a typewriter, and also forreleasing the carriage for more extendednnovements when it is desired topermit the carriage to make the required movements for tabulatingpurposes.

Fast on the escapernent arbor 11 between the escapement ratchet whee122and the pulley -13 there is a. gear pinion 30, and between `thecseapcmcnt.

thc pinion 3() and the pulley 13 the arbor 11 cxtcnds through a bearingformed in an upright plate 251 carried by brackets ft2 made fast to alixed part 32 of the maip frame 1. .\t the rcar or outer end of thearbor 11 and exterior to the pulleyr 13 there is secured a` pinion 33 inmesh with a gear wheel 34 mounted on a stud carried by the plat'e'fi'l,the said stud forn'iing a journal bearing for a rock arm 3G having a hub37 at one end through which the stud 35 extends. While the pinion 38 andgear wheel 34 may be sccured in. place against accidental removal in anyIsuitable way, screws 38 and ii!) resine tivcl \v constitute convenientmeans for holdin#r thc pinion Sill fast to thc arbor ll and thc gearwheel 34 upon thc stud fi so as to bc rolnlcd thcreon blv thc pinionlili. The arm Bti has a latc|'all \l oifsct portion 4t) provided on thcedge toward the pivot (nd of the arm 3H with a recess 41. ihile thcportion 4U may be made in one piece with the arm ISU, it may bc madeseparatcl)r therefrom and secured thercb blv screws 42 or otherwise.livotallv mounted on thc arm 3o by means oi' a pivot screw 43 or an)-other appropriate manner. is a pawl 44 .having a tooth 45 arranged toengage between the teeth of thc gear wheel 34. and the pawl 44 iscontinued beyond thc tooth 45 to form a nose 4G extended across therecess 41. Arranged to move in'to and ont of thc recess 41 when thc arm36 is in a certain position and when lodged in the recess 41 arranged tohold the arm against rocking movements. is a finger 47 projecting from arock member 48 pivotcd al the end remote from the finger 47 on a rod 49carried by the brackets 32. The rock member 48 is provided with an angleextension 50 carrying a roller 51 so located as to extend above theplane ot' the upper edges of the brackets 32, and the rock member 48 isconstrained to movein one direction by a spring 52 fast at one end tothe rock member and at the other end to one of thc brackets 32. Thenormal tendency of the finger of the rock member 48 under the action ot2the Spring 52 is to rise out of the recess 41. The purpose of the rockarm 36 and the parts described with reference thereto will appearhereinafter.

Tt is customary in typewriters of the gen eral class to which thepresent invention relates to employ a rack bar for the control of themovements of the carriage by the power spring as permitted by theactionof ln connection with the present invention there is provided a rack bar53 made fast at. thc ends by screws 54. or otherwise, in return endmembers 57 ot' an elongated rectang 1,'ulaiframehaving one long sidelnember 56,- whieh ma; be in one piece with the end members 55, whilethe other longr side of the frame in tbc main voneisie of the rack har53, the teeth of which are directed toward the side menthe).- Jt' of theframe.

Since the inesent imention has to do with tnhulating ineehzinim there isprovided e tahulator har 79 provided with un indexSO and with alongitudinal series of perforations or sockets 8l, in this respect beingsimi lar to known forms of tahulator hars. The present invention withrespectto the tabulator har differs from other structures in that thebnr 79 is provided with a longi` tudinal supportimgr att-ip 82 to whichit is vonneeted b v screws 83 or otherwise extending' throughlongitudinal slots 84 in the bar 75l. :o that the bar 79 hns :i limitedrange olA li'meitudinal movement equal to the length of the slots 84.,Housed in a longitudinal noeliet 85 in the letrip 82 is n Spring .Sticonnected at one end by a stud 87 to the ntrip Si, and .at the other endby a stud 88 to the her TU. the spring tending at all times to maintainthe har at one .limit of its travel.

Monnte'l on studi` 8 9 Carried by 'the Strip 82 are rollers 90 enteringelongated pockets 91 in the har 79, and other rollers 92 seated in thestrip hold the har 79 in slightly spaced relation to the strip 82, sgthat the bar 79 is almost; wholly supported with re spect to the strip82 by anti-friction means, when-foro the movement of the har 79 alongits supporting strip S2 is extremely easy.

The strip 82 is supported at the ends by angle arms 93, 94,respectively, each arm beinar connected at one end to a respectlve endof the strip 82, and at the other end pivotally mounted as by screws 95and 9G, respectively, on respective brackets 97 and 98 made fast to thetop of the main frame Y1, by screws or otherwise.

In the particular arrangement shown in the drawings the angle arms 93and 94 are approximately U-shaped, so as to extend around certain partsof the-particular machine to which the invention is shown as applied,but such particular shape is not necessary in all styles of typewritermachines, nor

is it essential that the supporting arms be angle arms when employed inother styles of typewriter machines. The supporting angle arm 94 isshown as provided with an extended portion 99 carrying at its free end aswivel nut 100 into which is screwed one threaded end of a link 101, theother end being engaged by the corresponding end of a key lever 102pivotally ,supported on the main frame by a pivot screw 103, and thiskey lever is ot' a length to have the key end 104 located within thespace provided for the keyboard 0f the machine.V In the particularstructure shown in the drawings this key is located at the right handend of the keyboard as viewed by the operator. The angle arm 94 has alsosecured to it an elongated finger 105, this finger extending in a direc-"tion lengthwise of the bar 79, and is provided for a purpose which willhereinafter appear. The bar 79 may be provided with a suitable number ofpins 1.06 adapted to any of the pin-receiving holes or sockets 81, andthesepius are designed to coact with an overhanging stop member.107 onthe upper end of a post 108 made fast to the bar G2 at an appropriatepoint thereon. The post 108 has a foot portion 109 with elongated slots110 for the passage of fastening screws 111, while set screws 112carried by the foot portion 109 and entering the slots 110 provide forthe accurate adjustment of the sto 'finger 107 with respect to thetabulator bar 9;

Since the strip 82 and the bar 79 constitute in effect, except for thelimited movement of the bar 79 on the strip 82, a compound tabulator barwith ,one Vmember longitudinally movable for a. very limited distance onthe other, and 'with thestrip constituting the support for the movablepin carrying member. theA term tabulator bar, or compound tabulator bar.dll be used hereinafter as generally descriptive of the rockable membercarried by the rockable angle arms 93 and 94 which in turn are pivotallysupported by the pivots 95and 90. The arrangement of the tahulator baris such that upon depressing the key 101 the tabulator bar is rockedtoward the front of the machine, so that the pin or pins 106 are then inthe path of the stop finger 107, and on the opening of the escapenientthe typewriter carriage is free to move under the action of the spring`8 in its usual or forward direction of travel until the stop 10T engagesa pin 106'in its path, and further movement of the carriage is therebyarrested.

At the end ol" the longitudinally movable men'iber T9 of the tabulatorbar there is secured a finger 1153, which, as will hereinafter appear,operates as an actuating linger for certain mechanism to be described.

ln accordance with the present invention there is provided a singlemanipulating key arranged to artuate mechanism constructed to move thetabulator bar into operative position, thon release the typewritercarriage to the action of the spring),r 8 for continued movement untilarrested by the appropriate pin 106 set in the tabulator bar,aml then toso adjust the carriage propelling mechanism that upon the normalmanipulation of the keyboard the carriage will travel in the op positeor reverse direction to its normal direction of travel. Such a key maybe located at any convenient part of the keyboard, or, in fact, at anyconvenient part of the typewriter machine, but in the particular showingof the drawings a combined tabulating and reversing key 114 is locatedat the let't hand end of the keyboard as viewed by the operator. rlhekey 111 is at one cud of a double or compound lever composed of twosimple levers 115 and 110, cach ot' the tirst order, and connectedtogether at their niet-ting.;r ends by a pivot pin 11T workingr in alongitudinal slot 118 in one of the levers, say, the lever 115. and saidlever is carried by a bracket 119 fast to'the main frame of thetypewriting machine, or may be otherwise supported by a pivot pin 120,which in the particular showing of Fig. 4 is indicated as working in aslot 121 in the member 115. The lever 116 is mounted on a piyot pin 122,either secured directly on a fixed portion of the machine, or upon abracket 123 made fast, to a fixed portion of the machine, Springs 124:2land 121h each fast at one end to a fixed part of the machine and at theother to the connected ends of the compound lever tend constantly tomaintain the key 114 in the elevated osition, but yield to pressureapplied to tie key 114. for its dcpression. At the end of the leversection 116 remote from its connection to the lever section 115, a link124 is connected at one end to said end of the lever section 110, andthis link 124 extends upwardly through the rear portion of the frame ofthe machine and is in turn threaded through a swivel nut 125 carried byone arm 126 of a broken lever. said lever having another arm 127 mountedon and projecting from the saine pivot pin or screw 128 carrying the arm126. and in the particular showing of the drawings this pivot pin ismounted on a. bracket 129 erected on the top of the frame of themachine. The 111111126 is provided with a stop 130 extended int-o thepath lof the arm 127, and a spring 131 made fast at one end to the arm126 and at the end to the arm 127 tends-cow stantly to maintain the arm127 against the stop 130, so that the two arnis 126 and 12T act a leverof the first order when opposed by any forces insutlicient to extend thespring 131.

Mounted on the bracket 129 by means of a pivotl pin or screw 132 is arock ineinlier 1551.1 having at. one end a laterally offset nose 134 inoverriding relation to the lever arm 12T,y and on the side of the pivotpin 1:12 remote from the nose 134 provided with an extension 135 havingat the end an adjust` able stop member in the form of g1 screw 1136, Therock arni 133 with its nose 134 is designed to operate aS an adjustablestop limiting the swinging of the lever arm 12T in one direction, andthis lever arm is so located with rete-renee to thc angle arln orsupport OIE as to underride this arm to the rear of the pivot 95thereof, and the free end ot the lever arm 12T engages a shoulder 13T onthe support 9:1 in such manner that when the lever arm 12T is rocked inontl direction, that is. toward the stop nose 134i.y the talmlator haris in turn roehed to'ivard the active position, so as to bring the pinor pins loo in the path ot' the stop 10T movable with the carriage. 1nthe drawingsl the shoulder 13T is shown as made separatelvY from and atlarhed to the supporting roeli alnrll)` hut it will he understood thatit ma)Y be an integral part ot' the arm or support itil.

Projecting rearwardly from the plate lll near the upper portionthereol1V and at the end of the plate remote from the level' arms 126and 121. is. a pivot stud 143 which may be in the form of a screw, andmounted at one end on this stud is an elongated roch arm 144 extendingacross the rear face of the plate 19 below the stud 25' and between theescapement dogs 23 and 24 and the correspoiuling face of the plate 19.That end of the arm 144 remote from the stud' 143 has connected theretoby means of a pivot 145 another roclc arm 146, while` the correspondingend of the rock arni 144 is formed with an extended stop member 147 iuthe path of the arm 146. The arm 146 is normally constrained to remainin contact with stop 147 by a spring 148 connected at one end to alaterallyv extended portion of the arm 144, and at the other end to thearm 146, but this spring will .yield to permit independent movement ofthe arm 146 on the pivot 145 in a direction away from the stop 147. Inthe particular construction shown in the drawings the plato 19 islocated nearer the rear end of the t'vpewi'iting machine than the arms126 and 127, and the arm 146 is singularly offset, as shown at 14th sothat its free extremity 150, that isl` the end reinote from the pivot.pin 145, is substantially in alineinent with the leg 139. The ei:-tremitv 1.70 carries an opstanding block 151 leaning away from theextremityY at an angle thereto, and pivoted in this block so to hangpendcutly therefrom is a. dog 152 having a terminal tooth extension1555' normally in the path ot' the taper extrelnit) or toe 140 ot' theleg 1B!) The dog 152 is normallyv urged toward the leg 130 liv a spring1:14 housed in the block 151` and the .spring permits yielding ot' thedog 1.12 l'or a sullicient distance to permit the toc 146 and nose 153to pass each other. To take any lateral strain from the pivots 143 and145 the, end 1.10 otE the arm 146 is guided bv an upsfinding bracket 155erected ou thel top ot the frame of the typewriter machine. and providedwith an elongated guiding reA cess 156 permitting rocking movements ofthe arni 146 in a substantially vertical plane about the pivot. 115which is horizontal. or about the pivot 1151 which is also horizontal inthe ordiniuw' workin;r position ot' the t vpe\vriting nlnehine.

Pivotally mounted on the plate 1S) on the same face as the arm 157, butat the other end of the plate, is a bent lever 160 having one end 161extending through an elongated recess 162 in the guide 1.35. the arm 161 being parallel with the arm termination 150 and having its free endin the path of the terminal portion 138 of the lever arm 126. The lever160 is connected to the plate 19 by a pivot stud 163, and has a shortarm 164 in the path of that end of the arm 157 remote from its pivotsupport, said end being do'wnturned as shown at 165 to engage the end164 of the lever 160.

Pivot ally mounted on the plate 19 on the same face as the arm 144 is alever 1.66 the pivotal mounting of the lever being shown as in the formof :L screw stud 167, but may be of any other construction. The lever166 has a shorter arm 168 so related to the roel: arm 144 as to lie inthe space between the arm 144 and the plate 19, and at the free end ofthe arm 168 it carries a pin 169 projecting through the arm 144 and intothe matching recesses 26 of the dogs 23 and 24. The pin 169 may be roundand the recesses in the dogs :23 and :24 may each be of semi-cardioidshape, so that the pin on moving into the more contracted end of thecombined re eesses tends to spread the dogs apart.

The lever 166 has its longer arm extending away from the plate 19 towardthe opposite. side of the typewriting machine from the lever arms 126and 127, and this long arm 166 of the lever is first bent, as shown at170, toward the top of the frame of the machine. and then for a distancesubstantially parallel therewith, and finally at substantially rightangles toward the front of the machine, the last-named end of the leverbeing shown at 171. A spring 172 connected at one end to the frame ofthe machine and at the other end to the long arm of the lever 166 nearthe pivot 167 tends to maintain the lever 166 with the pin 169 raisedout of the path of the dogs 23 and Q4. and with the long arm of thelever depressed. The end 171 of the lever 166 is in the assembledmachine in4 the path of the free end of the elongated finger 105. sothat when the tabulator bar is rocked from the inactive toward theactive position, which movement raises the finger 105, the lever 166 isrocked on its pivot against the action of the spring 172 in a directionto cause a spreading of the dogs 23 and 24 out of engagement with theratchet `wheel 22, thus releasing the escapement arbor 11 and permittingthe spring 8 to turn the drum or wheel 9 1n a direction to Wind the band14 thereon, and thereby actuate the escapement arbor in a direction toimpart movement to the typewriter carriage by means of the gear Wheel 22and rack 53 in the ordinary or normal direction until this movement isarrested by the engagement of the stop 107 with a pin 106 in its path.Since the rock arm support 94Lof the tabulator bar is directly under thecontrol of the ordinary tabulating key 104, a manipulation of suc key104 releases the :carriage for movement to the desired tabulatingpositions in the customary' manner. operations may be performcdby thekey 114 in a manner which will hereinafter be' described, but forreasons which will also hereinafter appear, it is desirable at times, toprovide for the tabulating movements of the carriage without bringlngabout certain other conditions resulting from the operation of the key114, and, therefore, the lever 166 is provided connecting up thestructure of the present invention with the customary tabulating ke 104.Otherwise the lever 166 might be omitted, for then the arm 144 in itsmovements will cause the same spreading or release of the dogs 23 and 24as is accomplished by the lever 166. The lever 166, however, is usefulin connection with the present invention even were the tabulating key104 omitted.

Mounted on the upper end of the post 141 by means of u pivot screw 172is a short rock arm 173 fast at the end remote from the pivot on one endof a rod 174, this rod extending across the back portion of the machine1n front of and at a short distancr from the plate 19. The other end ofthis rod is fast to one end of an angle lever 175 pivotally supported bya pivot screw or pin 176 to the upper end of an upright post 177 risingfrom the top of the frame of the ina-- chine, and made fast thereto. Thelever 175 has its short arm connected to the rod 174. this short armbeing of the same length as the rock arm 173, while the long arm of thelever is formedl with a return bend 178 entering between the legs of aV-shaped rocker 179 mounted on the post 177 by means of a pivot screw orstud 180. One arm 181 of this rocker 179, .and constituting the shorterarm, engages over the return end 173 of the lever 175, the parts beingrounded to reduce friction. The rocker 179 has the longer arm 182terminating in a laterally extended finger 183 underrlding the angleextension 171 of the lever 166. The rod 171 is overridden by one end ofa lever 184 made fast to an appropriate part of the carriage 2 by a clip185, while the other end of the lever is in the path of a rock member186 customarily present in typewriting machines of the kind illustratedin the drawings and under the control of escapement release1 {ingerpiece 187, When such release finger The same tabulatngg` tit? mit

the screw 22.1 as a center, while at one side of the plate is anoutstanding ear 223 in thev path of a stop pin 224 carried by the crankarm 216 near the handle 217. The stop ear 223 determines the movement ofthe crank arm 216 inone direction, while the limit of movementofthe-"l'ide 202 in a direction oposed to the"spri,ng 205 may determinethe imit of movement of the crank arm in the other direction, or this`crank arm may be stopped at such 'limit by any suitable means.

Between the bearing bracket 214 and an adjacent fixed portion of theframe 1 traversed by the shaft 213, said shaft is surrounded by a spring225 having one end made fast to a fixed part of the frame of themachine, and the other end to a set collar 226 made fast to the shaft213, so that on turning the shaft by means of the ,crank arm 216, thesprin 225 is put under superior tension, and w en the crank arm 216 isreleased the spring returns the shaft to its first position with thestop pin 224 in engagement with the ear 223.

The shaft 215 extends through and to the rear of the bearing 214 and atsuch point has fast thereto a hub 22T from which there extends a radialarm 228, and this arm has pivotally connected thereto as by a screw 229a link 230 provided at the end remote from the arm 228 with an elongatedslot 231. The slotted end of the link may be curved and the slot have alike curve, and extending through this slot is a headed pin or screw 232fast in the outer end of the arm 3G.

In the position of the parts shown in Fig. 2 the arm 36 is at the limitof its movement in one iirection, being there held by the engagementbfthe finger 47 in the notch o'r recess 41, and the slot 231 is longenough to permit movement of the arm 36 toward the right, as viewed inFig. 2, for van appropriate distance, for a purpose which will-hereinafter appear.

With n machine constructed as described a depression of the key 114causes the carriage to be released for quick movement to the columnposition desired, and this movement is not to the beginning edge of theeolumn, but to the opposite or final edge thereof, and the feedingmechanism for the carriage is so adjusted that upona manipulation of thekeys of the typewriter, the writing is performed in a direction thereverse of or contrary to the normal writing direction of movement. Forinstance, in typewriting a column of figures representing sums of money,or any other figures, the carriage may be brought to either the decimal.or the cents position, as mayl be needed, and then the sums of moneyare typewritten, beginning with cents and then proceeding to dollars,tens, hundreds, thousands, etc., in the order named. This insures theproper arrangement in the columnof various sums of money with the samedenominations of each sum immediately under those of the preceding ones,and this without effort or calculation on the part of the operator, andwithout the necessity of ascertaining the spacing of each sum of moneyto determine at what point it is necessary to begin writing the amount.Vith the ordinary typewriter it is necessary in order to have varioussums of money in column form all end at the same point to calculate thebeginning point of writing each sum. Vith the present invention thetabulating devices automatically establish the point of beginning thewriting ,of each sum of money, and then automatically reverse thecarriage feed, so that the operator has but to write down the sum ofmoney, beginning with the lowest amount of the sum, and writing towardthe higher amounts, but using the typewriter otherwise in the ordinarywa Suppose, now, t at it is desired to Write a'column of figures wherethe numerals are all to be properly placed with respect one to the otherfrom the top of the column to the bottom, a pin 106 is placed in thetabulating bar at the position it is predetermined shall represent theright hand side of the typewritten column, and which for convenience ofdescription may be considered as the decimal point.- Of course, whensums of money are being written, it is customary to set the pin twospaces further on to include cents, but this` is to be understood in theidea of beginning the writing of the column at the decimal point. Thefirst thing for the operator to do when ready to begin Writing thedesired numbers is to depress the key 114.v This moves the compoundlever 115, 116 against the action of the spring 124, and this movementthrough the rod or link 124 causes a depression or' the free end of thelever arm 126. In Fig. 7 the lever arm 126 is shown in the normalp`osition of rest with the end 140 n short distance from the toothli) ofthe dog 152, so that the arm 126 may have a short extent of movementbefore engaging the tooth 153. This movement is imparted to the leverarm 127, and the end of this arm engaging the shoulder 137 causes arocking movement of the angle support of the tabulator bar, so that thistabulator bar is moved forwardly until the pin 106 corresponding to thedecimal position is in the path of the stop 107. Then the end 140 of thelever arm 126 by engagement with the tooth 153 causes a rocking movementof the arms 146 and 144, at the time connected to move as one arm, bythespring 147 the same as the arms 126 and 127 move together because joinedby. the spring 131.
